Convert spline

Can you convert a spline line back into a normal line/polyline?

EXPLODE perhaps?

This should answer your question more than adequately:

I have tried explode to no avail

Ye cheers ReMark.

This was one of the solutions on that link that worked

Save As R12DXF - If you save a drawing as R12 DXF format, all splines will be converted to POLYLINE entities.

Thanks again!

Quickly written, may help in future:

You're entirely welcomed JDB but the credit really goes to R.K.M. I only passed along his excellent advice. Glad to hear you got your problem solved.
